To all whom it may concern:

Be it known that we, FRED W. SNOW and Asa B. CUMMINGS, citizens of theUnited States, residing at Bryantville and South Hanson, respectively,in the county of Plymouth and State of Massachusetts, have in ventedcertain new and useful Improvements in Sand-Spreading Devices; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art towhich'it appertains to make and use the same.

The present invention relates to sand spreading devices or machines andis designed particularly for' use in spreading sand upon cranberry bogs.

The object of the invention is to provide a sand spreading machine bywhich sand can be spread rapidly and evenly over a cranberry bog withoutinjury to the bog.

With the above object in view, the present invention consists in thedevices, combinations and arrangements of parts hereinafter describedand claimed, the advantages of which will be obvious to those skilled inthe art from the following description.

A sand spreading machine embodying the several features of the presentinvention in their preferred form is illustrated in the accompanyingdrawing in which;

Figure 1 is a plan view of the machine; Fig. 2 is a view in sideelevation of the machine; and Fig. 3 is a detail sectional view taken onthe line 33 of Fig. 1.

The machine, as illustrated, comprises two troughs l in which the sandis placed. These troughs are rigidly connected together and extend inparallel relation to each other. The two troughs are supported by asupporting wheel 4 located between the troughs, the axis 5 of the wheelbeing arranged at right angles to the troughs so that the troughs can bemoved along longitudinally over the surface of the bog. The troughs arealso provided with supporting legs 6 at their rear ends and these legsare so proportioned with relation to the diameter of the wheel 4 thatwhen the legs are resting on the ground the troughs are supported in asubstantially horizontal position. At the rear ends of the troughs,handles 7 are provided by means of which the rear ends of the troughscan be lifted to raise the legs 6 from the ground and bring the troughsSpecification of Letters Patent.

into an inclined position to cause a flow of troughs and deliver it overthe tops of the rollers. As illustrated in the drawing, this meansconsists of a wheel 9 rigidly secured to the shaft 10 carrying therollers 8. The wheel 9 is smaller than the wheel i and is so arrangedthat it can be brought into contact with theground or raised therefrom.lVhen in contact with the ground the wheel 9 is revolved and the sand isdistributed evenly by the rollers 8. To stop the delivery of sand thehandles 7 are lowered sufliciently to remove the wheel 9 from theground.

To regulate the flow of sand to the rollers 8, a controlling device isprovided in each trough consisting of a shaft 11 provided with radiallyprojecting pins 12, which shaft is located in the troughs a shortdistance to the rear of the roller 8. The shaft 11 is rotated in adirection opposite to the direction of rotation of the rollers 8 byintermeshing gears 13 and 14 on the shafts l0 and 11 respectively.

As shown in Fig. 1, the two troughs are separated a distance equal tothe width of one of the troughs. By arranging the troughs in this mannerit is possible to sand two strips of hog simultaneously, and to coverthe whole bog without spreading two layers of sand on any portion of thebog. The manner in which the machine is used to sand a hog will bereadily understood if it is con sidered that the bog is divided up intoa series of strips, each the width of one of the troughs 1. In startingthe sanding operation the wheel 4 will be caused to traverse the middleof strip number two, and thus strips one and three will be sanded. Thenext trip of the wheel 4 will be along strip number three, and thusstrips numbers two and four will be sanded The next trip will be alongstrip number six, and thus strips five and seven will be sanded, and onthe next trip strips six and eight will be sanded. In like manner theother strips are sanded until the entire surface of the bog is covcred.

The preferred embodiment of the present invention having beenspecifically described, what is claimed is 1. A sand spreader having, incombination, a trough, a fluted roller at the delivery end of the troughextending above the bottom of the trough, and means for rotating theroller in a direction to raise the sand from the trough and deliver itover the top of the roller.

2. A sand spreader having, in combination, a trough, a fluted roller atthe delivery end of the trough extending above the bottom of the trough,means for rotating the roller in a direction to raise the sand from thetrough and deliver it over the top of the roller, and a device forcontrolling the flow of sand to the roller.

3. A sand spreader having, in combination, a trough, a fluted roller atthe delivery end of the trough extending above the bottom of the trough,a supporting wheel for the trough, and a driving wheel for the flutedroller arranged to be brought into engagement with the ground by tippingthe trough.

4. A sand spreader having, in combina tion, a trough, a fluted roller atthe delivery end of the trough extending above the bottom of the trough,a supporting wheel for the trough, a driving wheel for the fluted rollerarranged to be brought into engagement with the ground by tipping thetrough, and a rotary device for controlling the flow of sand to theroller driven by the driving wheel.

5. A sand spreader having, in combination, a trough, a fluted roller atthe delivery end of the trough extending above the bottom of the trough,means for rotating the roller in a direction to raise the sand from thetrough and deliver it over the top of the roller, a shaft provided withradially extending pins arranged to control the flow of sand to theroller, and means for rotating the shaft in a direction opposite to thedirection of rotation of the roller.

6. A sand spreader having, in combination, a trough, a wheel and legsfor supporting the trough in substantially hori zontal position, afluted roller at the delivery end of the trough extending above thebottom of the trough, means'for inclining the trough to cause a flow ofsand toward the roller, and means for rotating the roller in a directionto raise the sand from the trough and deliver it over the top of theroller when the trough is in inclined position.

7 A sand spreader having, in combination, two troughs, a supportingWheel located between the troughs with its axis at right angles to thetroughs,a sand delivering roller at the front end of each trough, meansfor inclining the troughs to cause a flow of sand toward the rollers,and means for rotating the rollers.
